Buffett says stocks and real estate should be treated as a long-term asset class where, even though prices go up and down, the most important thing is to buy when Mr. Market is less interested.

NEW YORK ( TheStreet) -- It's no surprise Warren Buffett's Annual Shareholder Letters always provide a "necessary trace of wisdom" that seems to satisfy the appetites of a variety of value investors. However, in the most recent shareholder letter, Buffett offers up some savvy advice directed at real estate investors.

In an exclusive excerpt from his upcoming shareholder letter, Buffett looks back at a pair of real estate purchases and the lessons they offer equity investors. Buffet explained an investment in a 400-acre farm near Tekamah, Neb., that he bought in 1986 for $280,000. In addition, he wrote about a strip center that he and his partners acquired in 1993 from the Resolution Trust Corporation.

Buffett explained that both deals had been bought at distressed pricing levels and that the two investments were "solid and satisfactory holdings for my lifetime and, subsequently, for my children and grandchildren."

Market Timers are Speculators

In real estate terms, investors often substitute the words "margin of safety" for "buy low, sell high" and as Buffett explained in the letter, "the unleveraged current yield from the property was about 10%...and its income would increase when several vacant stores were leased. Even more important, the largest tenant -- who occupied around 20% of the project's space -- was paying rent of about $5 per foot, whereas other tenants averaged $70. The expiration of this bargain lease in nine years was certain to provide a major boost to earnings. The property's location was also superb: NYU wasn't going anywhere."

Of course we know that Buffett was not boasting about his sharp shooting real estate investments. Instead he was purposely providing practical advice for long-time value investors. Buffett was explaining that stocks and real estate should be treated as a long-term asset class where, even though prices go up and down, the most important thing is to buy when Mr. Market is less interested.

Buffett explained that folks that seek immediate gratification are like market timers and investors should keep "things simple and don't swing for the fences. When promised quick profits, respond with a quick 'no.'"

Buffet added, "If you instead focus on the prospective price change of a contemplated purchase, you are speculating."
